Q: Question: Which game that used the LaserDisc video for the background sold the most copies? Passage:Other LaserDisc video games followed the lead of Astron Belt by integrating more and more computer graphics with the pre-recorded video. For example, Funai's Inter Stellar in 1983 was a forward-scrolling third-person rail shooter that used computer graphics for the ships and full-motion video for the backgrounds. Similarly, M.A.C.H. 3 and Cube Quest were vertical scrolling shooters that used the LaserDisc video for the background and computer graphics for the ships. The Firefox arcade game included a Philips LaserDisc player to combine live action video and sound from the Firefox film with computer generated graphics and sound. The game used a special CAV LaserDisc containing multiple storylines stored in very short, interleaved segments on the disc. The player would seek the short distance to the next segment of a storyline during the vertical retrace interval by adjusting the tracking mirror, allowing perfectly continuous video even as the player switched storylines under control of the game's computer. This method of seeking was noted for being extremely strenuous on the player and frequently led to the machines breaking, slightly hindering the appeal of LaserDisc arcade games. In the 1990s, American Laser Games produced a wide variety of live-action light gun LaserDisc video games, which played much like the early LaserDisc games, but used a light gun instead of a joystick to affect the action.
